摘要： A puffer type gas-blast circuit breaker provided with a movable electrode and a fixed electrode opposite the movable electrode, which electrodes are separable for implementing a circuit-breaking action, and a fixed current-carrying contact arranged around the periphery of the fixed electrode. The movable electrode is equipped with a surrounding insulating nozzle having a tapered inside surface. Movement of the movable electrode during separation of the electrodes compresses the gas in a puffer chamber and so blows out the resulting arc between the movable and fixed electrodes. The circuit breaker further includes a cylindrical insulator or capacitor that surrounds the arc extinction chamber formed by the electrodes and the insulating nozzle between the movable and fixed electrodes. In the circuit-breaking action, the line of extension of the tapered inside surface of the insulating nozzle downstream, as regards the gas flow, from the throat portion of the insulating nozzle, and extending in the direction of the fixed contact, lies within the innermost portion of the extreme end portion of the fixed current-carrying contact, on the side of the fixed contact nearest the movable electrode.

摘要： A direct current interrupter comprising a plurality of two-point interrupter units each including a pair of interrupting portions. The interrupting portions of the interrupter units are arranged at regular angular intervals on a circle with the axial line of the interrupter as its center and arranged parallel to the axial line. An input terminal is provided to supply shunted current to one interrupting portion of each interrupter unit. An output terminal is provided to receive the shunted current from the other interrupting portion of each interrupter unit. A first common connecting portion and a second common connecting portion near the axial line. The main current flows through a conductor line from the main current input terminal to the first common connecting portion and shunted. The shunted current is supplied to the input terminal of each interrupter unit, flows through the two interrupting portions of the interrupter unit in the opposite directions, and is delivered from the output terminal of the interrupter unit. The shunted current flows through the second common connecting portion and delivered from the main current output terminal.
